FAQ’s

Why do I need a Waterproof Bag?

Our Waterproof Bags were designed to hold the undies you’re not wearing, whether that’s the fresh pair you’re planning to change into, or the used pair you need to keep hold of until you’re able to wash them. Slimline and discreet, we love them in our handbag or school bag to ensure we’re never caught short.


When should I use a Laundry Bag?

Ideally, every time you wash your Modibodi, you should pop them in a laundry bag. This helps to protect them in the washing machine and will prolong their lifespan. 

Care Guide

Step 1. Wash your Modibodi before wearing them for the first time. This will activate the technology in the gusset for maximum absorbency.

Step 2. Rinse in cold water after use <30° Do not soak, just rinse until the water runs clear!

Step 3. Cold wash (now or later) In a delicates bag is even better!

Step 4. Hang dry. Reuse. Repeat! Go you eco warrior!

Step 5. Hold the fabric softener. This reduces the product’s function!

"Modibodi was the best thing that ever happened to me."

Overall very good.

Great product, works as described and comfy. Tends to roll down so could do with a wider waistband.

Ingenious product

Every woman should have these in their drawers. Gives such peace of mind in work, everyday life and especially night time. I fully intend to buy more. Would be a fantastic product to give to teenage girls.

Problème de taille

Le tissu étant particulier il est pas très élastique, il met du temps à se détendre et reste toutefois très serré. Je n'ai pas pu l'essayer car contrairement à un autre modèle de la marque la taille ne correspondait pas malgré la prise de mesure avant l'achat.

Par contre point positif, la partie absorbante et imperméable monte bien tout le long des fesses. Si elle remontait aussi jusqu'en haut devant, elle aurait été parfaite du point de vue couvrant !

Modibodi UK

HI Karla!

Thanks for your review! Our Seam free range uses heat fusing tape on the legs and waist instead of elastic. This is what gives the smooth, no VPL finish. Because of this, they may seem quite tight when putting them on for the first time. We recommend giving the waist a little stretch before trying on to activate the tape. You may need to shimmy your way into them, but once on, they will stretch out as you wear them! Please wash them first though - this activates our absorbency!
